+GIT v1.5.4.7 Release Notes
+==========================
+
+Fixes since 1.5.4.7
+-------------------
+
+ * Removed support for an obsolete gitweb request URI, whose
+   implementation ran "git diff" Porcelain, instead of using plumbing,
+   which would have run an external diff command specified in the
+   repository configuration as the gitweb user.
